This was the junction between the Peebles Railway of 1855 and the Penicuik Railway of 1872. The junction was to the south of a level crossing immediately south of Rosewell and Hawthornden station.
The junction also served Whitehill Colliery which had exchange sidings on the east side of the line, south of the level crossing. The colliery closed in 1961, abandoned 1962, the closure of the line south to Peebles and Galashiels at the same time perhaps not being a coincidence. The box remained open until 1964 as the Penicuik Railway remained open and this box was not only a gate box but the end of the double track section from Hardengreen Junction. In 1964 the line was singled. It closed in 1967.
On the west side of the junction was a short siding for the Gorton Colliery. This was named, along with Gorton Crossing (the level crossing here), for Gorton House which is to the north.
